I think I’d just bring extra food the next day so both I and they can eat. Clearly someone isn’t able to bring their own food for whatever reason, and I can’t really blame them for choosing to eat when the alternative is starving, even if it is annoying that I missed my lunch that day.
I’ll take the imperialist extraterrestrials, they’re probably gonna be easier to mobilize humans in opposition against than the terrestrial imperialists we have now.
